Expert Solution & Answer
Chapter 9, Problem 20SA
Explanation of Solution
Sets:
- • The set is an unordered collection of unique elements.
- • The set may contain different types of data; it can be numbers, characters, strings, and also class objects.
- • In Python, “set()” method is used to create the sets.
Subset:
- • If two sets are given, then if one set contains some or all the elements of other set, then that set is called the subset of other set.
- • The “issubset()” method can be used to check whether one set is a subset of the other.
Syntax:
In Python, the method “issubset()” can be used to check subset, and it can expressed as follows:
set1.issubset(set2)
Program:
#create the set set1 with five elements
set1 = set([100, 200, 300, 400, 500])
#create the set set2 with three elements
set2 = set([200, 400, 500])
#check whether set1 is subset of set2
print('set1 is subset of set2:',set1.issubset(set2))
#check whether set2 is subset of set1
print('set2 is subset of set1:',set2.issubset(set1))
Explanation of the program:
In the above Python code,
- • The first statement is to create the set “set1” using the “set()” function; the “set1” contains “100”, “200”, “300”, “400”, and “500”.
- • The second statement is to create the set “set2” using the “set()” function; the “set2” contains “200”, “400”, and “500”.
- • The third statement is to check whether “set1” is a subset of “set2”; if the result is “true”, it means “set1” is a subset of “set2”.
- • Here, the result is “false”; thus, “set1” is not a subset of “set2”.
- • The fourth statement is to check whether “set2” is a subset of “set1”; if the result is “true”, it means “set2” is a subset of “set1”.
- • Here, the result is “true”; thus, “set2” is a subset of “set1”...

1) set1 = set([10, 20, 30, 40])
set2 = set([40, 50, 60])
set3 = set1.union(set2) set4 = set1.difference(set2)
set5 = set2.difference(set1) set6 = set1.symmetric_difference(set2) print(set3) print(set4) print(set5) print(set6)
What is the output of the print statements?
IntSet unionWith(const IntSet& otherIntSet) const;
//Unions the current set with the passed set. IntSet::unionWith(const IntSet& otherIntSet){ for (int i = 0; i < otherIntSet.used; ++i) //For each element in the passed set. { add(otherIntSet.data[i]); //Add it to current set. }}
Write a program that asks the user toenter two non-empty sets and display their intersection and union.
Design the following function in the program:
set_intersection–This function gets the intersection of two given sets.
set_union–This function gets the union of two given sets.

This is now the function that frees (destroys) a dictionary: void dict_destroy (dict_t* dict); This operates just as dict_clear, but in addition should free the memory that was allocated during dict_create. After a call to this function, if any other library function receives the pointer dict, the behavior is undefined (most likely, it will crash).
